Definitions
- the invention relates to a method for cleaning and establishing or restoring a hydrophobic effect of textiles in a domestic washing machine with facilities for heating a washing liquid present in an outer tub and for controlling treatment processes, as well as with detergent chambers, of which at least one is configured to hold an individual dose of a liquid detergent, with which method water-repelling agents dissolved in the washing liquid are brought into contact with the textiles during a treatment process similar to a washing process, with which method
- the invention also relates to a washing machine for implementing such a method.
- water-repelling agents are available, which are suitable for use for waterproofing textiles in domestic washing machines. Such agents primarily consist of fluorocarbon resins or agents containing paraffin.
- the textiles to be waterproofed should be cleaned thoroughly beforehand in a separate wash program. Waterproofing is then carried out separately in the known manner in a standard washing process in a so-called long washing liquid, which is characterized in that a relatively large amount of washing liquid is used per kg of washing.
- a recommended quantity of water-repelling agent is thereby introduced into the main wash chamber of a detergent dispenser before the start of the standard washing process and supplied to the outer tub of the washing machine together with cold fresh water.
- the movement of the washing due to the rotation of the washing drum causes the waterproofing washing liquid to come into contact with the washing, while said waterproofing washing liquid is being heated by a heating device in the outer tub.
- the duration of this treatment is thereby predetermined by the program of the washing machine controller and is for example also defined by the reaching of the predetermined temperature of the waterproofing washing liquid.
- the washing is rinsed a number of times, so that the quantity of waterproofing agent attaching to the textile fibers of the washing is further reduced.
- the hydrophobic effect that can be achieved with the known method is therefore relatively minor.
- the process for establishing or restoring waterproofing is carried out completely separately from any other treatment process in the washing machine, so the user of the washing machine has to carry out the loading and setting operations twice and also has to wait for the full duration of both separate treatment programs.
- the object of the invention is therefore to set down a method, which can be used in a domestic washing machine and with which the user of the washing machine has at their disposal a treatment sequence, with which the textiles can be both cleaned and waterproofed in a continuous processing program. Also the intention is to improve the hydrophobic effect that can be achieved significantly compared with the prior art with a continuous processing program.
- this object is achieved by the features set out in the exemplary embodiments in the manner that a washing process for cleaning the textiles is carried out with the addition of a special detergent, which in addition to its known dirt-removing effect is also suitable for removing any detergent agents still present from the textiles, into a quantity of fresh water flowing in, and at the end the used washing liquid is pumped away, that after the end of the washing process a multi-stage rinsing process is carried out for the textiles as the respective washing liquid of the previous process is replaced and that after the end of the rinsing process, as the last rinsing washing liquid is being replaced and the water-repelling agent is being added to a newly supplied quantity of fresh water, a treatment process is carried out to waterproof the washing.
- a washing machine for implementing the inventive method or one of its developments is also set down.
- This washing machine has input means, which can be used to select a program sequence for the washing machine, with which the method operates automatically and a control facility is provided, which is used to control the selected program sequence automatically, as soon as a start signal is present for this purpose.
- FIG. 1 shows a schematic diagram of a washing machine with an outer tub and a washing drum supported therein to hold textiles and
- FIG. 2 shows a diagram of the time sequence of a washing process as the first part of the complete run-through process according to the invention
- FIG. 3 shows a diagram of the time sequence of the inventive method immediately following the washing and rinsing processes, to waterproof the textiles that have just been cleaned.
- the outer tub 1 in FIG. 1 contains a washing drum 2 supported therein about a horizontal axis 3 and having agitators 4 for the washing 7 , which consists of textiles.
- the agitators 4 have scooping facilities, which can be used to scoop washing liquid 6 from the bottom of the outer tub 1 during rotation of the washing drum 2 in the arrow direction 16 from a level N V , which is above the lowest point of the washing drum 2 , raise it to a level above the washing 7 and spray it down from there onto the washing 7 . This accelerates the wetting and flow through the washing 7 .
- An electric motor 14 serves to rotate the washing drum 2 , inducing its rotational movement into the washing drum 2 by way of a belt drive.
- a heating facility 13 is disposed at the base of the outer tub 1 , serving to heat the washing liquid.
- This washing liquid 6 is introduced into the outer tub 1 by activation of one of the magnetic valves 8 or 9 and consists either only of water or a mixture of water and detergent.
- Two chambers 111 and 112 are shown in the detergent dispenser 11 , through which fresh water flows respectively when the assigned magnetic valve is opened. Detergent in the chambers is then transferred by the water through the pipe 10 out of the detergent dispenser 11 into the outer tub 1 . Washing liquid 6 , which is at the bottom of the outer tub 1 , can be conveyed out by the discharge pipe 17 and pump in a manner not shown in more detail here.
- All the switchable or controllable facilities such as the magnetic valves 8 and 9 , the heating facility 13 , the drum drive motor 14 and the drain pump 18 , are switched or controlled by the control facility 12 of the washing machine.
- a temperature sensor 15 is also used to measure the temperature of the washing liquid 6 , transmitting its measurement signals by way of the control circuit to an evaluation facility 121 in the control facility 12 .
- the washing machine illustrated in FIG. 1 includes input means 122 are present, which can be used to preselect a program sequence for the washing machine, with which the method operates automatically.
- the control facility 12 controls the preselected program sequence automatically, as soon as a start signal is present for this purpose.
- the input means 122 can include, for example, one or more of a rotary selector, dial, input button, or other known input device or actuator, etc.
- the washing machine illustrated in FIG. 1 is for example operated in the manner illustrated in FIGS. 2 and 3 .
- the scale on the ordinate only applies to the rotational speed of the washing drum 2 ; no scale is assigned to the other parameters.
- the magnetic valve 8 is opened to introduce water by way of the detergent chamber 111 —in this example filled with special detergent for the preparatory cleaning of items of washing to be waterproofed—and the pipe 10 into the outer tub 1 .
- the water carries this special agent with it into the outer tub 1 , where it is distributed.
- the washing drum 2 is only driven at a rotational speed (e.g. 23 rpm), which is lower than is the case after wetting, according to the bold continuous line n on the diagram. Also in the wetting phase PhB the drum 2 is only driven in arrow direction 16 , in which the scooping facilities 5 on the shell of the drum are fully effective.
- the washing drum 2 is driven in a constantly reversing manner, for example at 50 rpm, so that the washing comes into contact in an intensive manner with the washing liquid, which has already been heated in the wetting phase.
- the washing liquid is pumped away and replaced with a fresh water/washing liquid mixture.
- the inflowing water can for example be routed through the already emptied detergent chamber 111 for this purpose.
- the rinsing phase PhSp includes a number of stages, with repeated filling with fresh water, so that the washing liquid becomes very significantly diluted. In fact if possible there should be no special detergent residue remaining in the washing. The number of rinsing stages should therefore be adjusted to meet this requirement.
- the waterproofing process follows immediately after the washing process according to FIG. 3 .
- the quantity of water introduced in the first phase PhI 1 is based on the batch of washing 7 in the washing drum 1 minus a quantity remaining in the washing from the rinsing process, and a further quantity required for the subsequent introduction of the water-repelling agent.
- This quantity of water passes once again by way of the magnetic valve 8 through the already emptied detergent chamber 111 into the outer tub, where it is first heated. Only when the washing liquid temperature reaches around 30° or 40° C.
- the waterproofing washing liquid 6 (diagram line V) is heated in the outer tub, according to the thin diagram line ⁇ before the addition of the water-repelling agent, by the heating facility 13 to a temperature of maximum 30° or 40° C.
- the waterproofing washing liquid is mixed thoroughly and distributed evenly in the batch of washing 7 . Because the washing is pre-wet in the preceding rinse PhSp, when the water-repelling agent is added, the suddenly resulting concentration of the waterproofing washing liquid cannot adversely affect the washing 7 ; nor is it now likely to produce the otherwise possible marking caused by high concentrations of agent.
- the drum movement initially ceases and the drain pump 18 starts to operate. This causes the free waterproofing washing liquid in the outer tub 1 to be sucked out through the discharge pipe by the pump 18 and drained away.
- the drum is switched to spin mode. In the diagram shown the high rotational speeds are shown compressed for reasons of space. However three spin pulses with respectively rising final rotational speeds can be identified, causing more and more bound washing liquid to be driven out of the washing. In the last spin interval the final spin speed can reach 800 rpm.

Abstract
Description
-
- a washing process for cleaning the textiles is carried out with the addition of a special detergent, which in addition to its known dirt-removing effect is also suitable for removing any detergent agents still present from the textiles, into a quantity of fresh water flowing in, and at the end the used washing liquid is pumped away,
- after the end of the washing process a multi-stage rinsing process is carried out for the textiles, as the respective washing liquid of the previous process is replaced and
- after the end of the rinsing process (PhSp), as the last rinsing washing liquid is being replaced and the water-repelling agent is being added to a newly supplied quantity of fresh water, a treatment process is carried out to waterproof the textiles.
-
- for a treatment process for waterproofing, the outer tub is filled with a quantity of water measured for a short washing liquid, in other words for a ratio of weight of the quantity of dry textiles to weight of the quantity of water of less than 1:8, and
- the washing liquid is heated to a temperature of at least 30° C., as the textiles are moved in the outer tub,
- before the water-repelling agent is added.
